I am confused on what i am comparing.
I find the calculated Req with the uncertainty... so I am comparing that to the measured, but i am confused on what to do with the uncertainty.
I need to find the discrepancy and say if it is signi. or insigni.

For Parallel i found, 22.5 -22.3 = 0.2 and the error was 0.141
So its Sig. But the rest confused me.

What equations did you use? There would be a couple ways to measure resistance, and a couple ways to find the error. If you used [tex]R = \frac{V}{i}[/tex] or any number of other equations for resistance then you would be able to find the uncertainty with the master rule for uncertainty, which is [tex]\pd q = \sqrt{(\frac{\partial q}{\partial x}\delta x)^2 +... + (\frac{\partial q}{\partial z}\delta z)^2[/tex] for whatever variables you have.

You could also use standard deviations for uncertainty, which would be my suggestion.
